Title: Positron generating device
Inventor: TANAKA HIROBUMI
IPC: G21K1/00
Filed: 1994-03-31
Abstract: PURPOSE:To generate a large quantity of positron beams in a positron generating device to analyze surface of samples and defects in grids. CONSTITUTION:Though each isotope 1 placed in line on the plane generates a few positrons, the lined isotopes generate a large number of positrons in total. The positrons which have entered a moderator 3 go perpendicularly out of the surface of it. Since the center of the moderator 3 is placed on the lower side, the positrons focus on one point. The positrons radiated from the moderator 3 are focused further and guided to a transporting component on the lower side by electric fields generated in extraction electrodes 4 to generate a large quantity of positron beams.

Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To keep system performance to an optimum state by waveform equalization processing reproducing signal waveforms of the same input from respective equalizers, measuring a mean value, a diffusion value and a distribution of transmission characteristics of a magnetic recording system, comparing output signals from respective equalizers setting equalization constants reflecting these statistical values and reproducing the data based on the compared result.

Abstract: PROBLEM TO BE SOLVED: To obtain a heat developing device capable of suppressing the occurrence of density unevenness and stabilizing the density by once lowering the temperature of a heating member before heat development of the next heat developing material after heat development of a previous heat developing material, then heating the heat developing material to the prescribed heat development temperature. SOLUTION: A film is stripped from the outer peripheral surface of a drum 14 by a guide plate 202a after the outer peripheral surface temperature in the central part of the drum 14 is once lowered. The stripped film is sent from a discharge port 202 of the film to a cooling section 150A. A drive assembly moves a movable frame 203a inward in a radial direction in such a manner that a cooling roller 203 comes into contact with the outer peripheral surface of the drum 14. As a result, the temperature of the outer peripheral surface of the drum 14 falls at a time. When the temperature falls, the drive assembly retreats the cooling roller 103 from the outer peripheral surface of the drum 14 to prevent the useless temperature fall.  The outer peripheral temperature of the drum 14 is thereafter elevated by heating with a heater 32 and is made uniform in the longitudinal direction of the drum 14.

IPC: C04B35/64
Filed: 1991-03-07
Abstract: PURPOSE:To provide the subject sintered compact little in deflection, good in roundness and cylindricality. CONSTITUTION:A solid or cylindrical form is first placed at the hollow part of an unsintered cylindrical form. This solid or cylindrical form has the following characteristics: (1) the outer side dimension at the maximum sintering temperature is equal to or greater than the inner side dimension on shrinking due to sintering the unsintered cylindrical form; (2) the thermal expansion coefficient is larger than that of the objective cylindrical sintered compact; and (3) heat resistance is higher than that of the objective cylindrical sintered compact. Thence, the unsintered cylindrical form is sintered to obtain the objective cylindrical sintered compact <=20mum in the inside roundness and <=50mum in the cylindricality of the inner diameter, just after sintered. Because of being good in the roundness and cylindricality, the sintered compact thus obtained can directly be used as a shaft sliding member for metallic rolls, sink rolls, or support rolls of molten metal plating devices, or as a sleeve for die casting machines.

Title: Position detector for underground excavator
Inventor: SHIBATANI KANJI
IPC: G01C21/04
Filed: 1989-03-17
Abstract: PURPOSE:To achieve a higher horizontal position detecting accuracy by compensating for a temperature characteristic of a circuit in the apparatus. CONSTITUTION:A signal generation means generates a signal with a frequency thereof the same as that of an alternating current to be supplied to a magnetic field generation cable 10 laid on a ground surface. The signal generated and outputs of a pair of coils 1 and 2 are switched with first and second switching circuits S2 and S3. First and second receivers perform specified reception processings of outputs of the circuits S2 and S3. Then, prior to a measurement of a horizontal displacement, inputs of the circuits S2 and S3 are switched to the side of the signal generation means. Then, first, a ratio is determined between outputs of the first and second receivers as obtained when the same signal is inputted to the receivers. Thereafter, outputs of the pair of coils 1 and 2 are inputted and, for example, one of the outputs of the receivers is multiplied by an inverse of the ratio obtained. Thus, based on a correction factor obtained by multiplication by the inverse and a value not subjected to the correction, a horizontal displacement of an underground excavating machine is measured to compensate for a difference in temperature characteristics between the first and second receivers.

Abstract: PURPOSE: To enable the working of the curved surface bent in the direction of feeding a table by moving upward or downward a grinding wheel synchronizing the position of the table with a signal transmitted to a NC controller from a position detector of a NC surface grinder.  
     CONSTITUTION: A table 4 loaded with work 2 reciprocates in the axis X by a hydraulic means, a motor or the like. A grinding wheel 1 runs straight in the axis Z under a NC control to flat the surface 3 to be ground of the work 2. Hence, a position detecting section 5 located in the axis X of the table 4 transmits a table position signal to a NC controller, which provides a command to a servo mechanism to drive and control the grinding wheel 1 in the axis 2 synchronizing the position of the table according to a preset program. Thus, the surface ground is made curved, not simply plane thereby enabling a crowing working.
